This invention relates to the water-heater in which the water circulatesthrough an inclosure containing steam heated pipes. J

Certain objects of the invention are to securegreater efficiency andeconomy in the use of the steam; and to increase the durability of theheater.

Other ob ects Wlll appear in connection 7 i withthe followingdescription:

Referring to Figs. 1, 2, 3, and 4 of the drawings, lis the main casing,of general circular form in, cross-section, which casing is supportedupon a hollow base, 2, from which it is separated by a horizontal plateor diaphragm, 8. The casing, 1, is provided near its lower end with awater-inlet, 4:, and at its upper end with a water-outlet, 5. Thecasing,x1, is surmounted by a head, 6,

containing an outlet passageway, 7, commu nicating with thewater-outlet, 5. Within the upper end of the casing, 1, is a steamdome,8, conforming to, but smaller than,

J Specification of Iletters Patent. Patented June 8, 1915 Applicationfiled. July 8, 1914. Serial No. 849,848. 6 I Y to receive the upperreduced screw-threaded ends, 10, of a like number of verticalsteamplpes, 11, the lower ends of whichpass down through correspondinglylocated apertures 1n the horizontal base-plate, 3, within whichapertures the lower ends of the respective- .pipes are expanded to makea tight joint.

the: dome at the apex thereof, and extends upward therefrom through aclose-fitting aperture in the head, 6, forming a sliding joint with thehead, 6 which joint is made steam-tight and water-tight by means of apac'kin'g, 13,and gland, 1 1.

The aperture in the head, .6, through which the inlet steam-pipe, 12,passes, is cov ered by an elbow, 15, bolted upon the top of the head, 6,with which'elbow is detachably connected a steam'supply-pipe,16, havingacontrolling valve, 17 whereby the supply of steam canbe regulated. Theelbow, 1,5, 7

thus forms a cap covering the aperaurein the head independently ofsaid'steam-inletpipe so as not to interfere with'the movements of thesteam-inlet-pipe. due to expansion and contraction. N

For certain purposes of the invention the cap for the aperture inthe'head', 6, may be of any desired form, such as not to interfere withthe movements of thesteam-inlet-pipe, while providing a means ofconnection for the main steam-supply-pipe,.but I prefer the elbow-formshown or some similar form whereby a [steam-chamber is formedsomewhatlarger than, and communicating with, the opening in thest'eam-inlet-pipe.

In the use of the heater, steam is introduced from the pipe, 16, passingdown through the steam-inlet pipe, 12, in somewhat expanded form andthence into the dome, 8, where it further expands and from which itpasses down through the pipes, 11,

within which it is condensed,- the water of condensation draining intothe hollow base,

2, from which it is conducted by a wastepipe, 18. The water entering thecasing at 4 flows around the steam-pipes, 11, and upwardly between thedome, 8, and the top of the casing and out through the passageway, 7,absorbing in its course both the sensible and the latent heat from thesteam which is condensed and converted into water in passing downthrough the pipes, 11. By connecting the passageway, 7, with the waterinlet,4:, by means of a return pipe in a heating system, not shown,circulation of the water may continue in the usual manner.

Byintroducing the steam at the top of the heater through the pipe, 12,the first action of the steam is at substantially its maximum ofsensible. heat uponthe outflowing water at its maximum temperature;while the steam is not subjected to the minimum temperature of theinflowing water until it reaches the lower portion of the pipes, 11,where it condenses, giving off its latent heat which quickly heats theinflowing Water.

The sliding joint at the stufling-box formed by the packing, 13, andgland, 14c,

affords freedom for expansion and contraction of the pipes, 11, avoidinginjurious strains upon the connections between said pipes and thebottom, 9, of the dome and horizontal base-plate, 3.

In the form of my invention shown in Figs. 5 and 6, the casing, 1, hasan integral head, 19, and is provided with an outlet passageway,20,through the head at one side of the casing. The steam-dome, 21, ismounted eccentrically within the casing nearer the side from which thepassageway, 20, extends, and the top, 22, of said dome and the head, 19,of the casing are preferably substantially flat and parallel with eachother. The space between the dome, 21, and easing, 1, through whichspace the heated water rises, becomes gradually restricted on the sidetoward the outlet passageway, 20, thereby tending to deflect theupwardly flowing water around the dome away from the outlet passagewayand into the space, 23, between the top of the dome and the head, 19,thus causing much of the outflowing water to traverse a devious I pathover a large area of the heated dome,

21, in reaching the outlet passageway, 20. Steam may be. supplied to thesteam-inlet pipe, 12, in any known manner. As the steam-domeis free torise and fall in ac eordance with the movements of expansion andcontraction of the pipes, 11, there is practically no tendency for theconnections between the steam-pipes and the dome and the bottom orbaseplate, 8, to become loose.

The stufling-box formed by the packing,

13, and gland, 14, is readily accessible for,

adjustment or renewal by removing the inlet-elbow, 15. r
